• Description:
  The Hamburg wheel-tracking device can be used to predict the moisture susceptibility of a hot mix asphalt (HMA) pavement. This report shows how the test results are influenced by compaction temperature and anti-stripping treatment. The higher the compaction temperature, the better the results in the Hamburg wheel-tracking device. The use of hydrated lime and liquid anti-stripping additives improved the results in the Hamburg wheel-tracking device over HMAs that were not treated. Hydrated lime dramatically improved the HMAs that were not treated. Liquid anti-stripping additives improved some of the HMAs dramatically while other HMAs were only improved slightly. These variables are important to control in the laboratory environment to ensure repeatability of the test. Additionally, these variables are also considered important to the moisture resistance of a pavement in the field.
